Yamaha F425 V8 5.6l XTO Offshore

Yamaha has built an enviable reputation for building highly reliable, technology driven, big horsepower engines and have now taken this to the extreme with the release of the all-new 425 horsepower, Yamaha XTO Offshore outboard.

Designed from the ground up to deliver maximum power and thrust. Powered by a big bore, 5.6 litre, naturally aspirated engine, the XTO Offshore opens up a whole new class of large outboard driven boats, delivering a more reliable, fuel efficient and premium quality engine solution.

The XTO Offshore is not only Yamaha's most powerful outboard, it is also their most technologically advanced, with the introduction of Yamaha's first fully integrated power system. This system combines a revolutionary fully integrated electric steering system, with a premium CL7 multifunction display, advanced 'drive-by-wire' throttle controls and Helm Master joystick docking and positioning controls - creating a truly effortless boating experience.

Other key features include an in-water gear lube change system, oversized rugged gear case and hardened gears, massive 90 Amp power-generation system and large diameter XTO OS high thrust prop.

The wraps are off the new Yamaha XTO Offshore outboard platform. The all-new outboard, rated at 425 HP, features a 5.6-litre V8 powerhead with direct fuel injection. The XTO sets a new benchmark for displacement and power from Yamaha.

The XTO Offshore, which in Yamaha-speak is called the XF425, will be available beginning in August, and will be sold alongside the Yamaha F350C outboard model, which will remain in production. Note, however, that according to Yamaha the XTO Offshore 425 produces 150 percent more thrust than the F350. This is a new level of performance from Yamaha.
